AL-FEC in a nutshell...

This site deals with Application-Level Forward Erasure Correction codes, or AL-FEC (also called UL-FEC, for Upper-Layers FEC). The idea, in one line, is to add redundancy in order to be able to recover from erasures. Because of their position in the communication stack, these codes are implemented as software codecs, and they find many applications in robust transmission and distrituted storage systems.
